The method includes receiving, on a first serving cell, at least one of a first UL grant and a first Physical HARQ Indicator Channel (PHICH) about a second serving cell through a cross-carrier scheduling, and receiving, on the second serving cell, at least one of a second UL grant and a second PHICH about the second serving cell through a self scheduling. According to aspects of the present invention, in a TDD-FDD carrier aggregation deployment environment, an efficient UL scheduling/HARQ operation may be performed for a UE in which a cross-carrier scheduling is configured. Further, in order to satisfy high data rate required by a UE, data transmission efficiency may be enhanced in accordance with the purpose of carrier aggregation (or dual connectivity)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus of uplink scheduling and HARQ timing","description":"The present disclosure relates to an apparatus and method for controlling an uplink (UL) scheduling and Hybrid Automatic Repeat reQuest (HARQ) timing supported in a TDD-FDD CA environment.
